Łódź vs Pearl

Informations

Łódź (Polish: [wutɕ] (listen)), written in English as Lodz, is the third-largest city in Poland and a former industrial centre. Located in the central part of the country, it has a population of 679,941 (2019). It is the capital of Łódź Voivodeship, and is located approximately 120 kilometres (75 mi) south-west of Warsaw. The city's coat of arms is an example of canting, as it depicts a boat (łódź in Polish), which alludes to the city's name. Łódź was once a small settlement that first appeared in 14th-century records. Despite being granted town rights in 1423, it remained the private property of the Kuyavian bishops and clergy until the late 18th century. The Second Industrial Revolution brought rapid growth in textile manufacturing and in population due to the inflow of migrants, notably Germans and Jews. Ever since the industrialization of the area, the city has struggled with multinationalism and social inequalities, which were documented in the novel The Promised Land by Nobel Prize-winning author Władysław Reymont. The contrasts greatly reflected on the architecture of the city, where luxurious mansions coexisted with redbrick factories and dilapidated tenement houses.

The industrial development and demographic surge made Łódź one of the largest cities in Poland. Under the German occupation during World War II, Łódź was briefly renamed to Litzmannstadt in honour of Karl Litzmann. The city's large Jewish population was forced into a walled zone known as the Łódź Ghetto, from which they were sent to German concentration and extermination camps. The city itself sustained insignificant damage during the war and became Poland's temporary seat of power in 1945. Łódź experienced a sharp demographic and economic decline after 1989. It was only in the 2010s that the city began to experience revitalization of its neglected downtown area. Łódź is ranked by the Globalization and World Cities Research Network on the “Sufficiency” level of global influence and is internationally known for its National Film School, a cradle for the most renowned Polish actors and directors, including Andrzej Wajda and Roman Polanski. In 2017, the city was inducted into the UNESCO Creative Cities Network and named UNESCO City of Film.

A pearl is a hard, glistening object produced within the soft tissue (specifically the mantle) of a living shelled mollusk or another animal, such as fossil conulariids. Just like the shell of a mollusk, a pearl is composed of calcium carbonate (mainly aragonite or a mixture of aragonite and calcite) in minute crystalline form, which has deposited in concentric layers. The ideal pearl is perfectly round and smooth, but many other shapes, known as baroque pearls, can occur. The finest quality of natural pearls have been highly valued as gemstones and objects of beauty for many centuries. Because of this, pearl has become a metaphor for something rare, fine, admirable and valuable. The most valuable pearls occur spontaneously in the wild, but are extremely rare. These wild pearls are referred to as natural pearls. Cultured or farmed pearls from pearl oysters and freshwater mussels make up the majority of those currently sold.

Imitation pearls are also widely sold in inexpensive jewelry, but the quality of their iridescence is usually very poor and is easily distinguished from that of genuine pearls. Pearls have been harvested and cultivated primarily for use in jewelry, but in the past were also used to adorn clothing. They have also been crushed and used in cosmetics, medicines and paint formulations. Whether wild or cultured, gem-quality pearls are almost always nacreous and iridescent, like the interior of the shell that produces them. However, almost all species of shelled mollusks are capable of producing pearls (technically "calcareous concretions") of lesser shine or less spherical shape. Although these may also be legitimately referred to as "pearls" by gemological labs and also under U.S. Federal Trade Commission rules, and are formed in the same way, most of them have no value except as curiosities.
